Ch'yah, it's a bottomless barrel, they don't delete your messages.
I don't use email alot, the only use it really has for me is communicating with wierd forces such as Maus. I use AIM to communicate in any way in general...or I pick up the phone :(

The max is five megabytes the last time I checked, or ten, but it was a while ago.
I'm pretty sure it's five, and if you use Picasa2 to send pictures through gMail it will let you send ten megabyte attachements.

Haha, I have six backup accounts, yeshyeshyesh.
That means I have over a thousand invites, because I have a lot more than six accounts :o

Well I did have more invites than most people a few months go. I decided to breed invites, and eventually I sold them all on Runescape (I played that just to pass the time for a bit) and made millions, haha. But oh well.

I have too many emails to manage, and then my "boss" wanted me to use the site's email, wondering if I can fwd that :o
